扫码、扫描二维码/条形码功能,自定义扫码界面视图,生成二维码/条形码
环境适配
swift 5.0+
ios 11.0+
请将以下添加到Package.swift的依赖项值中:
dependencies: [
.package(url: "https://github.com/CMlinksuccess/ScanCodePackage.git", from: "1.0.0")
]
在Podfile文件中添加:
pod 'ScanCodePackage' ,:git =>"git@github.com:CMlinksuccess/ScanCodePackage.git"
然后,执行下面命令:
$ pod install
- 调用扫码功能(扫描二维码/条形码、图片识别二维码/条形码、生成二维码/条形码)
- 自定义扫码界面UI(继承式自定义修改样式,完全自定义调用封装组件)
- 生成二维码/条形码
在info.plist中添加相关权限配置
<key>NSCameraUsageDescription</key>
<string>需要访问相机来拍摄照片</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>需要访问相册来选择照片</string>
<key>NSPhotoLibraryAddUsageDescription</key>
<string>需要访问相册以保存图片</string>
1、调用扫描页面,监听ScanBaseVCDelegate 实现结果回调
let scanvc = ScanBaseVC()
scanvc.delegate = self
self.present(scanvc, animated: true)
2、扫码样式类型
//MARK: 扫码区域类型
enum ScanAreaStyle {
case screen //全屏,或传入视图100%扫描
case angle //矩形框区域
}
//MARK: 扫码区域动画类型
enum ScanAnimationStyle {
case lineMove //线条上下移动
case grid //网格扫描
case lineStill //线条停放在中间位置
case none //无动画效果
}
//MARK: 扫码区域四角位置类型
enum ScanFrameAngleStyle {
case inner //内嵌,一般无矩形框显示效果
case outer //矩形框角上外嵌
case on //矩形框角上覆盖
}
扫码视图参数配置
//扫码视图参数配置
struct ScanViewStyle {
//扫码区域类型,默认为矩形框内识别
var scanAreaStyle:ScanAreaStyle = .angle
//是否显示绘制矩形框。默认true
var isShowRetangle = true
//区域宽高比,默认为1.0,即为正方形
var whRatio:CGFloat = 1.0
//矩形框中心偏移量,0为正中心位置
var centerUpOffset:CGFloat = 0
//矩形框左边距
var retangleOffsetX:CGFloat = 60
//矩形框线条颜色,默认为白色
var retangleLineColor: UIColor = .white
//矩形框宽度,默认为1.0
var retangleLineWidth: CGFloat = 1.0
//扫码框四个角类型
var angleStyle:ScanFrameAngleStyle = .on
//扫码框四个角颜色
var angleColor:UIColor = UIColor(red: 0.0, green: 167.0 / 255.0, blue: 231.0 / 255.0, alpha: 1.0)
//扫码框四个角宽高
var angleW: CGFloat = 24.0
var angleH: CGFloat = 24.0
//扫码四个角线条宽度
var frameLineW: CGFloat = 4
//扫描动画类型
var animationStyle: ScanAnimationStyle = .lineMove
//动画视图
var animationImageView:UIImageView?
//非扫码区域背景颜色
var backgroundAreaColor: UIColor = UIColor(red: 0, green: 0, blue: 0, alpha: 0.5)
init() { }
}
3、结果回调
默认结果回调
extension ViewController: ScanBaseVCDelegate {
func scanCodeBaseDidFinished(result: ScanResult?) {
print("扫码和图码识别完成的结果回调\(String(describing: result))")
}
func scanGenerateCodeImage(image: UIImage?) {
print("生成的二维码图片结果回调\(String(describing: image))")
}
}
全自定义模式结果回调
extension CustomizedScanVC:ScanCodeViewDelegate, ScanImageActionDelegate{
func scanCodeDidFinished (result: ScanResult?) {
print("扫码结果回调")
}
func scanImageDidFinished(result: ScanResult?) {
print("图片码识别结果回调")
}
}
4、生成二维码/条形码
//生成二维码
let image = generateQRCodeImage(content: "生成二维码的内容8993847349",size: CGSize(width: 200, height: 200), codeType: "CIQRCodeGenerator",codeColor: .green,bgColor: .white)
//生成条形码
let image = generateBarCodeImage(content: "7928347957wjer",codeType: "CICode128BarcodeGenerator")
//缩放图片大小
if let img = image {
let resizeImage = resizeImage(image: img, quality: .none, rate: 2)
}
scanResource.bundle
